Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the behavioral burden. It discloses the three areas being checked, which is useful, but it does not describe the output format, whether the check is read-only, or what happens on failure. The verb 'check' implies no mutation, but this is not explicit.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, well-structured sentence with no filler. It front-loads the action verb and lists the three check targets compactly. Every word contributes meaning, and it is neither verbose nor under-specified in terms of scope.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a zero-parameter diagnostic tool, the description names the core checked resources, but it lacks any mention of return values, success criteria, or how the results should be interpreted. Given the number of related tools, a brief note on when this health check is relevant would improve completeness. Still, the tool is simple and the scope is mostly covered.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has zero parameters, so the description has no parameter semantics to clarify. The baseline for a 0-parameter schema is 4, and this description does not introduce any confusing parameter-related information. No deduction is warranted.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses the specific verb 'Check' and names three concrete resources: Snapmaker Orca CLI, U1 profile discovery, and output directory access. This clearly identifies the tool's scope and distinguishes it from the many model, profile, slicing, and run-management siblings. It stops short of a 5 because it doesn't explicitly state that this is a pre-flight environment validation tool.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is given about when to run this tool versus alternatives, nor any indication it should be used before other operations. The description simply states what it checks, leaving the agent to infer the appropriate context. There are also no explicit exclusions or alternatives mentioned.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
